//构建POST请求请求地址请更换为自己的。
//1)

//文件路径请换成自己的
//2)

builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
//第一个参数为相当于 Form表单提交的file框的name值第二个参数就是我们要发送的InputStream对象了
//第三个参数是文件名
//3)
builder.addBinaryBody("uploadFile", inputStream, ContentType.create("multipart/form-data"), "text01.txt");
//4)构建请求参数普通表单项
